Transducer

What is a transducer?

A transducer is a device that converts the energy from one form to another. Usually, a transducer converts a signal in a form of energy to a signal in another.

Different types of transducer:

Classification based on the source of energy: Active and passive transducer 

Classification based on physical quantity: 

• Pressure transducer - Bourdon gauge
• Force transducer  - Dynamometer
• Acceleration transducer  - Accelerometer
